Australia Recap - How much did I spend??

I went to Australia for around a month with 4 main travel days This would be the price for two people give or take. ($5000 per person is my guess) Honesty i think i went a bit wild here but i was thinking how many times do you get to go to Australia in your life I could have saved $1000 or $1500 if i stayed at hostels instead of airbnb but 🤷🏼‍♀️
